LG has released the G2, a 5.2-inch phablet with its buttons on the back, which is already available on Verizon and AT&T. However, T-Mobile and Sprint customers are still awaiting a release date. When will the LG G2 see a release date on those carriers?

T-Mobile will begin selling the LG G2 in stores on Sept. 25. T-Mobile is offering the LG G2 in white and black, whereas Verizon customers will have an exclusive model with a differently designer rear shell, and a metallic “rear key” (back power and volume rocker) in addition to exclusive wireless charging for the device.

T-Mobile has priced the LG G2 at $603.99 -- with $99 paid up front and $21 added to customers’ monthly bill for 24 months. T-Mobile customers will get a free LG QuickWindow case with the G2.

Sprint will not release the LG G2 until Oct. 25, but will also offer a free QuickWindow case. The QuickWindow case works as a screen cover that interacts with the LG G2, protecting the screen while displaying apps resized from full view from the small window on the device. The time, messages and music controls can all be viewed from LG G2’s QuickWindow. The accessory retails for $49.99.

The LG G2 has a 5.2-inch, full HD 1080p display, with a 2.26 GHz, quad-core processor and 2GB of RAM. The LG G2 sports a 13-megapixel main camera and a 2.1-megapixel shooter on the front, and ships with either 16GB or 32GB of built-in storage, but lacks an SD card slot. The LG G2 has uniquely placed volume and power buttons, located on the rear of the device and dubbed the “rear key” by the Korean manufacturer.
